In 10 I tried a number of different offensive systems. Until I get my five-stars ten deep at every position I like to focus on power running and quick passes. I've never been a fan of the spread. Prefer to have a reasonably quick QB who can sell the PA and head for the corner if the receivers aren't open. This year the playbook is decent. They have some of the big I-form sets I like, but I also like to have at least 2-3 of I-strong and I-weak (the offset ones).
I'm a little tired of the defensive plays, honestly. In 09 and 10 I had it down to a science even on Heisman. If a team scored more than ten points it was a disappointment, and I still usually put up thirty plus.
Other impressions: The menus both in-game and out are a lot slicker. The game has a quicker feel to it. Like the no-huddle play system. I'm not going to rock the dynasty until I get the rosters this year, but I sense that EA could still find a way to offer a more create-your-own-story feel to the product. Unless I really missed something, they dropped all suspensions and stuff like that. There's not much RP value to the coach, either. You either win or you don't, and your reputation as a coach doesn't seem to matter much in recruiting unless the recruit has coaching prestige as a high interest pitch. Wouldn't mind seeing some kind of budget game added in, where you can upgrade your stadium. Winning increases TV revenue increases perks. Stuff like that.
NCAA is a great game, but they seem to be sweating all their bullets over the online side, which just about nobody I know uses. I don't use it much myself. It's a general trend in gaming I've never been a fan of. The game itself is what sells me; the online side is secondary. I'm still waiting for a truly immersive dynasty mode.
